I have a 99 chevy tahoe that is bagged and I am looking to building a box inbetween the rear tubs. In the picture it shows my measurement but will this be enough space for 2-15' FI Q? Those are inches not feet, sorry.

That is almost 10ft^3 before port or sub displacement. You should be able to fit both in there ported fairly easily and it is way more than enough room if you are using them sealed.

if you can go taller you can fit some bl's or even btls if you can wall it.... but it seems like you maybe trying to keep the box below the window line is that right?

Thanks, KHARPS

Trying to stay even with the top of the tubs. So I guess I am good on space for them two 15's FI Q. What about port dimensions, what will they be on these speakers it I was to port?

Thanks for the link. I have a question though, what will I use for the square port width and square port length 2?

square port width is how wide your port is going to be. The port length 2 is the part of the port thake makes the 'L', change it and see where your tuning goes down on the bottom. Honestly, this program can be off (not by much though) sometimes. It's good if you just want to get an idea of what you want, but i'd just take the time to do the math and figure it out myself, just my opinion though.

Thanks, I think I got it figured out.
